Pages 3 (753 words)
local area network (LAN). In other words, a LAN is a local computer network, which allows computers to communicate with each other. The network usually consists of computers, word processors, and other electronic equipment that allows different offices to communicate…
Extract of sample
Software can take the form of a centralized database, distributed application or can be a collection of simple utilities, which might be shared on a computer with in the domain. Similarly hardware can be a printer or a centralized storage device. LAN offers the fastest data transfer rate up to 10 Mbps.
Stair & Reynolds (2001) suggest that usually, LAN is wired into office buildings, factories, school buildings, etc and are built around personal computers (PC). When a PC is connected to a LAN, a network interface card (NIC) is required which is placed in a computer's expansion slot to allow it to communicate with the network. A wire or connector from the network is then plugged directly into NIC. (Stair & Reynolds, 2001, p. 138)
In order to install and configure a LAN setup in a school, the topology should have to be selected. Out of the three topologies, i.e. ring, bus and star, star topology is the most feasible one, as due to the failure of a computer or a segment of wire or a node, the other network nodes would not be affected at all. For star topology the basic hardware required for connectivity are as follows:
For a smaller LAN with a maximum of 10 computers Hub works fine but for a larger LAN a switch gives better efficiency compared to a hub. ...
